Macro mermaid 

macro_rules! mermaid {
    ($file:literal) => { ... };
    ($file:literal left framed) => { ... };
    ($file:literal framed left) => { ... };
    ($file:literal center framed) => { ... };
    ($file:literal framed center) => { ... };
    ($file:literal right framed) => { ... };
    ($file:literal framed right) => { ... };
    ($file:literal framed) => { ... };
    ($file:literal left) => { ... };
    ($file:literal right) => { ... };
    ($file:literal center) => { ... };
}

Include a mermaid diagram in the documentation.

This macro is meant to be used as argument of the #[doc] attribute.

/// Some documentation about a function
/// Then include a diagram:
#[doc = mermaid!("netflix.mmd")]
fn a_function() {}

This would produce:

Some documentation

Then include a diagram:

pie title NETFLIX
    "Time spent in menu" : 90
    "Time watching content" : 10

Look at the crate level documentation for all the options.
